Rose needs less "dere" and more "tsun". Her "SUKI! SUKI! SUKI! DAAAISUKI!" starts to become pretty annoying by now.
This series is still far from bad but my list of flaws gets longer each episode. The fights are extremely short and lack action, Rose in her current state and her (useless) companions have aparrently no chance to win against the black dragon - not even Ryuji with his overpowered dagger. But Rose combined with Ryuji´s super-duper-dagger are able to finish off the dragon in a single blow.
Congratulations! The main protagonist has successfully saved his maid in distress from the altar, destroyed the symbol of her engagement with the black dragon, defeated him a few minutes later, confessed his feelings to Rose and paired up with her. All that in a single episode
The third episode felt like the last one, but - oh wait - they haven´t kissed yet...
